Subsurface pullout guide for drawers, etc.

ABSTRACT

A subsurface pullout guide (10) with a guiding rail (12), constructed as a profiled rail, which is to be fastened to the carcass wall, and with a running rail (26), which is disposed in the region of the bottom of the drawer and supported longitudinally displaceably on the guiding rail by rolling bodies (20, 22), which are held in a cage (24). A hollow profiled section, the cross section of which is identical with that of the running rail (26), is hinged to the end of the running rail (26) within the carcass so that it can be swiveled from a first position, aligned with the running rail and directly adjoining its end within the carcass, into a second position, which extends, on the other hand, essentially parallel to the rear wall of the drawer. Interacting guiding means are provided at the guiding rail and the pivotable hollow profiled section, which swivel the hollow profiled section (30) during the shifting of the running rail (26) on the guiding rail (12) from the end position, assigned to the completely pulled out position of the drawer, in the direction in which the drawer is pushed in, as its end in the carcass approaches the rear wall of the carcass, increasingly into the second position, which is essentially parallel to the rear wall of the drawer.

BACKGROUND OF THE INVENTION

The invention relates to a subsurface pullout guide for drawers or thelike, which are supported in the carcass of a cupboard, wardrobe orcabinet and can be pulled out. The guiding rail of the pullout guide,constructed as a profiled rail and fastened to the wall of the carcass,engages from below the associated running rail, which is formed by ahollow profiled rail open at the underside and disposed in the region ofthe bottom of the drawer or the underside of the side wall of thedrawer. In the interior of the running rail, the pullout guide formsrolling surfaces for rolling bodies, which are held in an elongated cageand are capable of rolling along transporting paths of the guiding railson the one hand and on transporting paths formed by assigned regions ofthe inner surface of the running rail on the other and thus enable therunning rail to be displaced longitudinally relative to the guidingrail.

Because of the plurality of rolling bodies in the form of balls and/orrollers, which can be displaced spatially not only in the pulloutdirection but also at right angles thereto, drawer pullout guides of thetype in question here have the advantage not only of running easily andbeing able to carry high loads but also of having a high transversestability when fully pulled out, so that a drawer, supported by means ofthem in the carcass of a cupboard, wardrobe or cabinet, even when pulledout completely, has no noticeable play in the horizontal transversedirection. For this reason, such pullout guides are used to anincreasing extent for supporting drawers in high quality furniture. Itis also advantageous in this connection to have the possibility ofconstructing the hollow profile, used for the running rail, with a lowoverall height, so that the running rail, in the so-called "subsurfacearrangement", can be disposed within the side wall at the underside ofthe bottom of a drawer directly next to the side wall protrudingdownwards slightly beyond the bottom, if the side walls of the drawerare formed by hollow metal or plastic profiles, which are open at theunderside. By these means, it is possible to enlarge the width of thedrawer in comparison to the roller pullout guides, which must bedisposed between the outside of the side wall of the drawer and thefacing interior side of the supporting wall of the carcass. The cage,which holds the rolling bodies between the guide and the running railand fixes the mutual distance between them and which is usuallyconstructed from plastic, requires the travel of the pullout guides inquestion to be limited to a path, which is shorter than the depth of theassociated drawer, so that the rear wall of the completely pulled-outdrawer is still within the associated carcass of the cupboard, wardrobeor cabinet by the dimensions of the cage, that is, the pullout guides ofthe type in question here are so-called "partial pullouts". Especiallywhen the drawer is low in height and very deep, the rear region of thedrawer, which still lies within the carcass of the cupboard, wardrobe orcabinet in the pulled-out state, can then not be inspected easily and isnot very accessible. It would therefore be desirable to construct thepullout guides also so that they can be pulled out completely; theassociated drawer could then be pulled so far out of the carcass of thecupboard, wardrobe or cabinet, that its rear wall is flush with thefront surface of the carcass of the cupboard, wardrobe or cabinet. Anysuch guides of the type under consideration here, which can be pulledout completely and are available, are obtained practically as acombination of two simple pullouts into so-called "double pullouts". Forroller pullout guides, for which the overall height is of littleimportance, because the total height of the side wall of the drawer isavailable, such "double pullouts" are used on a large scale. On theother hand, in the case of the roller body-supported pullout guides,which are in question here and can be used in subsurface arrangement,"double pullouts" can be used only in special cases, since the verticaloverall height in the case of these pullouts is significantly greater,as a result of which the side walls of the drawer must protrude more orthe bottom of the drawer must be raised in relation to the height, atwhich it is disposed in the side wall, if the arrangement of runningrails is not to be visible in an undesirable manner at the underside ofthe drawer. With that, however, the capacity of the drawer is decreased.

In those cases, in which the capacity of the drawer is not as critical,attempts were also made with simple pullouts to attain the appearance ofa complete pullout, in that the drawer was shortened in the pulloutdirection approximately by the dimensions of the cage, whereas a runningrail of the largest length possible was used. The end regions of therunning rails, pointing to the rear wall of the carcass, thus protrudebeyond the rear wall of the drawer into the interior of the carcass.Since the protruding ends of the running rail are covered by the rearwall of the drawer, this is not noticeable for drawers supported in thecarcass of the cupboard, wardrobe or cabinet. However, the capacity ofthe drawers is, of course, decreased in proportion to the decrease indepth.

It was proposed for roller pullout guides that a complete pullout couldbe realized owing to the fact that, instead of inserting a furtherintermediate rail in the rear end of the running rail, an additionalrunning rail part, which can be tilted about a vertical or horizontalaxis, be added. As the drawer is pushed in and approaches the completelyclosed position, this additional running rail part is swiveled by aforced control about the horizontal axis in the upward direction orabout the vertical axis towards the inside in front of the rear wall ofthe drawer in such a manner, that the drawer can be pushed in further.When the drawer is being pulled out, the running rail part, then alignedonce again with the actual running rail, makes available an additionalpullout path, which permits the drawer to be pulled out completely(German Offenlegungsschrift 2946113). Such complete pullouts for rollerpullout guides have not gained acceptance in practice and, for thesubsurface pullout guide under consideration here with pullout guides,constructed as hollow profiles, being supported by roller bodies,complete pullouts have become known only in the form of theaforementioned "double pullouts".

Against this background, it is an object of the invention to develop thesubsurface pullout guides, which are under consideration here and therunning rail of which is supported on rolling bodies on the guidingrail, further into a complete pullout, without causing an increase inthe overall height in the vertical direction.

Starting out from a pullout guide of the type mentioned above, thisobject is accomplished pursuant to the invention owing to the fact that,at the end of the running rail within the carcass, a hollow profiledsection, identical in cross section with the hollow profiled crosssection of the running rail, is hinged so that it can be swiveled in aknown manner from a first position, in which it is aligned with therunning rail and which adjoins its end in the carcass directly, into asecond position, which extends, on the other hand, essentially parallelto the rear wall of the drawer and that, at the guiding rail and thepivotable hollow profiled section, interacting guiding means areprovided, which swivel the hollow profiled section during the shiftingof the running rail on the guiding rail from the end position, assignedto the completely pulled out position of the drawer, in the direction inwhich the drawer is pushed in, as its end within the carcass approachesthe rear wall of the carcass, increasingly into the second position,which is essentially parallel to the rear wall of the drawer.Surprisingly, it has turned out that the pivotable hinging of the hollowprofiled section at the rear end of the running rail, formed by a hollowprofile of identical cross section, can be carried out with a sufficientaccuracy, so that obstructions or stoppages do not occur even when thecage, containing the rolling bodies, passes over the interface betweenthe hollow profiled section and the running rail. On the other hand, anadditional pullout path is actually made available in this manner in thelength of the hollow profiled section and enables even comparativelydeep drawers, the rear wall of which, in the completely pushed inposition, is taken almost to the rear wall of the carcass, to be pulledout to such an extent, so as to compensate for the loss in pullout pathcaused by the cage, containing the rolling bodies.

The swiveling axis of the hollow profiled rail at the running rail caneither extend horizontally or also vertically in each case at rightangles to the shifting direction of the running rail on the guidingrail, the hollow profiled section, mentioned in the first case,preferably being hinged so that it can swivel from the position, alignedwith the running rail, into a position, in which it is swiveled uprelative to the aligned position, while in the second case there isswiveling away from the adjacent side wall of the carcass in front ofthe rear wall of an associated drawer.

To control the swiveling process of the hollow profiled section in apreferred further development of the invention, a control section,pointing from the longitudinal extent of the profiled rail in theswiveling direction of the hollow profiled section, is joined to the endof the profiled rail, which is located at the rear wall of the carcass,and forms the guiding rail, the guiding means then having a controlelement, which is provided at the hollow profiled section, and engagesthe control section upon approaching the closing action of the drawer.

Moreover, the embodiment may advantageously be such that the controlsection adjoins a longitudinal guide, which is provided at the guidingrail and engages the control element.

If the hollow profiled section is hinged to the end of the running railwithin the carcass in such a manner that it can be swiveled about ahorizontal axis, the longitudinal guide advisably is formed by a stripof material, which protrudes essentially at right angles into theinterior of the carcass from a profiled leg of the profiled rail,including the control section, which forms the guiding rail, and liesagainst and can be fastened to the carcass wall, and the control elementis formed by a projection, protruding from the hollow profiled sectionin the direction of the guiding rail and held at least against one sideof the material strip.

On the other hand, if the hollow profiled section is hinged so that itcan be swiveled about a vertical axis, the design advisably is such thatthe longitudinal guide is formed by a strip-shaped region of material ofat least one of the profiled legs of the profiled rail forming theguiding rail, which profiled leg or legs is or are reduced in height intheir end region within the carcass and transformed out of their course,parallel to the carcass wall, in the direction of the course of thecontrol section, and that the control element is formed by at least oneprojection, which protrudes from the hollow profiled section to theguiding rail and is held in contact with at least at one side of thestrip-shaped region or regions of material.

Moreover, the control element can also be formed by two projectionslying against opposite sides of the strip of material, as a result ofwhich a forced control of the swiveling process of the hollow profiledsection is then produced.

In any case, it is advisable to provide the projection or projections,at least in the region of its or their contact with the strip ofmaterial, with a friction-reducing surface, for example, a suitableplastic coating, in order to avoid binding when the drawer is pulled outor pushed in.

For this purpose, the embodiment can also be such that the projection orprojections is or are formed in each case by a control roller, which isrotatably mounted at the hollow profiled section and the peripheralsurface of which rolls along one side of the strip of material.

Particularly when the control element is formed by only one projection,held in contact with one side of the strip of material, it is advisableto put the hollow profiled section elastically under tension in thedirection of a swiveling motion from the first into the second position.This putting under tension brings about not only the contact between thecontrol element and the strip of material, but at the same time also, ifthe tension on the spring used is adequate, causes the drawer, onapproaching the closed position, to be pulled under the action of thespring into the completely closed position by the hollow profiledsection swiveling with respect to the running rail. This means that thefunction of automatically pulling in the drawer can be realized withoutadditional structural expense.

Because of the fact that the drawer, supported with the inventivepullout guides in a carcass of a cupboard, wardrobe or cabinet, can bepulled further out of the carcass of cupboard, wardrobe or cabinet thanit can usually with a conventional pull-out, the bending stress on therails of the pull-out guides is also increased in the completelypulled-out state, in which the overlap of the running and guiding rails,after all, corresponds essentially only to the length of the cage of therolling bodies. It is therefore advisable to provide at the end of theguiding rail outside of the carcass at least one projection, whichsupports the running rail in the completely pulled-out position of thedrawer and thus, in addition to the rolling bodies provided at the endof the cage averted from the rear wall, transfers the stresses, arisingin the completely pulled-out position of the drawer, to the guidingrail. Here also, it may then once again be advisable if the projectionor projections is or are provided at least in the region supporting therunning rail with a friction-reducing surface, it also being possiblefor the projection to be formed by a roller, which is mounted rotatablyat a profiled leg of the guiding rail guided into the interior of therunning rail and rolls along the inside of the cross member section ofthe hollow profiled forming the running rail.

In order to make it impossible for the drawer, together with the runningrail, to be pulled out of the carcass further than intended, it isadvisable to provide a stop for the control element at the end of thestrip of material, which is averted from the rear wall of the carcassand forms the longitudinal guide, with which stop the control elementcollides in the intended pullout position.

If the control element is formed by a control roller, the stop can beformed by an end section of the strip of material bent circularly tocorrespond to the radius of the control roller.

It is possible to do without the spring, which places the hollowprofiled section elastically under tension in the direction of aswiveling into the second position, if this swiveling into the closedposition takes place necessarily due to the appropriate construction ofthe control section. According to a further advantageous development ofthe invention, this can be attained owing to the fact that a controlcurve is formed between two boundary walls, which protrude towards thehollow profiled section and between which the control element isaccommodated and guided suitably.

In this case also, the control element is advisably constructed as acontrol roller, which is mounted so that it can rotate at the hollowprofiled section and the diameter of which essentially is equal to thedistance between the mutually facing surfaces of the control curveboundary walls.

In this connection, it is advisable to make the height of the mutuallyfacing surfaces of the control curve boundary walls the same as orslightly larger than the width of the peripheral region of the controlroller that is accommodated between these surfaces and to have shortstrips of material, which embrace the peripheral region of the controlroller somewhat on the hollow profiled section side, protrude from theedges of the boundary walls, facing the hollow profiled rail section, asa result of which the unintentional exit of the control roller from thecontrol curve is precluded reliably.

In this case, the control section advisably is constructed as a flatplastic component, which is provided at the end of the guiding railwithin the carcass, manufactured separately and fastened to the guidingrail.

Moreover, the control section preferably is produced from athermoplastic synthetic material, from the side of which, facing theguiding rail profiled leg provided for fastening the guiding rail to thesupporting wall of the carcass, short, integrally joined fastening pinsprotrude, which reach through boreholes in the profiled leg and aretransformed at their free ends by thermoforming into rivet heads.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1 to 3 show an example, labeled 10 as a whole, of a subsurfacepullout guide, constructed pursuant to the invention, in three differentpositions, namely a position of the running rail on the guiding railcorresponding to the closed position of the drawer, one corresponding toa partially pulled-out drawer and one corresponding to the completelypulled-out drawer, the outline of an associated drawer being indicatedin FIGS. 1 and 2 by a broken line.

The construction 10 has a sheet metal guiding rail 12, which is bentinto a gutter-shaped profile and the one, perpendicular, profiled leg 14of which can be fastened at the inner surface (not shown) of the sidewall of the carcass of a cupboard, wardrobe or cabinet, preferably byscrews. An extended, strip-shaped cross member section 16 is bentapproximately at right angles to the lower edge of the profiled leg 14.A further profiled leg 18 is bent upward from the edge of the crossmember section 16 averted from the profiled leg 14. The height of thisprofiled leg 18, measured in the vertical direction, is clearly lessthan the height of the profiled leg 14. By transforming the sheet metal,tracks for the rolling bodies are formed at the upper free edge of theprofiled leg 18 and, moreover, with rollers 20 having a horizontallydisposed axis and, on opposite sides to the rollers 20, downwardlyoffset balls 20, which are held so that they can rotate in a cage 24 ata given distance from and in a specified position relative to oneanother. The running rail 26, which is constructed as a hollow profiledrail with the cross section of an inverted U, is supported on therolling bodies so that it can be shifted longitudinally. In the presentcase, said running rail 26 is intended to be installed at the undersideof the bottom of a drawer 28 directly next to the side wall of thedrawer assigned to protrude below the bottom of the drawer. If the sidewall of the drawer is formed by a hollow metal frame, which is open atthe lower front side, the running rail 26 can also be inserted in theopen underside of this metal frame. To the extent in which it has beendescribed up to now, the pullout guide is identical with the knownpullout guides of the same type.

In an inventive further development, a hollow profiled section is hingedto the end of the running rail within the carcass so that it can beswiveled about an axis extending horizontally at right angles to thedirection, in which the drawer is pushed in. The cross section of thishollow profiled section 28 is identical with that of the hollow profileforming the running rail. The hollow profiled section 30 is hinged tothe end of the running rail within the carcass in such a manner, that itcan be swiveled between the two end positions shown in FIG. 4, namely afirst end position aligned against the end of the running rail 26 (seealso FIGS. 2 and 3) and a second end position swiveled upward throughabout 90° relative to the first end position (see also FIG. 1). Sincethe hollow profiled section 30 is joined to the end of the running rail26 grasping the drawer from below over the whole length of the drawer,it protrudes full length from the rear wall of the drawer 28 in thefirst end position. The swiveled position of the hollow profiled section30 is controlled, in a manner that will still be described in thefollowing, so that it is kept over the greater part of the pushing inand pulling out path of an associated drawer in the first end position,in which also the cage 24, holding the rolling bodies 20, 22, can passover at least partly from the running rail 28 into the hollow profiledsection 30 and vice-versa. Only when the drawer approaches the rear wallof the associated carcass of the cupboard, wardrobe or cabinet (notshown) to such a degree, that the free end of the hollow profiledsection 30 threatens to collide with the rear wall, is the hollowprofiled section 30 swiveled upward into the second end position. Thecage 24, holding the rolling bodies 20, 22, is then completely in therunning rail and does not interfere with this swiveling process.

In the vicinity of the free end of the hollow profiled section 30, acontrol element is provided in the form of a control roller 32, whichcan be rotated about an axis running parallel to the swiveling axis ofthe hollow profiled section 30. The peripheral surface of the controlroller 32 is pressed against a longitudinal guide, which is provided inthe upper edge region of the guiding rail 12 and is in the form of astrip of material 34 cut integrally at the leg 14 of the guiding rail 12and bent over at right angles into the interior of the carcass and whichis able to roll. A control section 36, connecting from the longitudinalextent of the guiding rail 12 obliquely in the swiveling direction ofthe hollow profiled section, is joined integrally to the carcass rearwall end of the profiled rail, forming the guiding rail 12. The materialstrip 34 continues in this oblique control section 36, and is roundedoff in the transition region between its horizontal extent at the leg 14and the oblique extent of the control section 36. In the region of thecontrol section 36, the material strip 34 is so wide, that it covers theperipheral surface of the control roller 32 completely. At the freeboundary edge of the material strip 34, that is, the edge averted fromthe profiled leg 14, a narrow strip-shaped, rectangularly bent section35 of material is joined, which embraces the control roller 32 laterallyand thus ensures that the control roller cannot slide laterally from thematerial strip and become jammed.

FIG. 4 shows that, at the hollow profiled section 30 on the one hand andat the rear end of the running rail 26 in the vicinity of the swivelingaxis of the hollow profiled section, a spiral spring 38 is disposed,which is under tension and normally forces the hollow profiled section30 into the second end position, that is, the position in which it isswiveled up and, at the same time, pushes the control roller 32 againstthe underside of the strip 34 of material. In the completely pushed-inposition of the drawer, the periphery of the control roller 32 thus liesat the outer upper end of the strip 34 of material, which protrudes fromthe control section 36. If the drawer is then pulled out, the controlroller 32 rolls along the strip of material and the hollow profiledsection 30 is swiveled increasingly in the direction of the first endposition, which is then reached when the control roller crosses overonto the horizontal section of the strip 34 of material. In the regionin which the control roller 32 is in the completely pulled-out positionof the drawer, the strip 34 of material is bent downward at 34a with anarc corresponding to the radius of the control roller 32, as a result ofwhich this end section 34a forms a stop, beyond which the running rail26 with the attached hollow profiled section 30 cannot be pulled outunintentionally. In this end position, the control roller 32 alsosupports the weight of the drawer and the contents of the drawer overthe strip 34 of material at the guiding rail 12. Moreover, it may beadvisable to provide an additional support between the running rail andthe guiding rail in this front end region by additionally having aprojection, provided at the guiding rail 12, support the guiding railfrom below in the fully pulled out position. By these means, the stresson the rolling bodies 20, 22 in the completely pulled out position isrelieved.

The spring 38 described above not only controls the swiveling process ofthe hollow profiled section 30 as the drawer 28 approaches the closedposition, but also causes the force of the spring, which is supportedover the control roller 32 at the strip 34 of material, to exert atorque, which acts in the pulling-in direction of the drawer. In otherwords, the spring 38 simultaneously realizes the function ofautomatically pulling in the drawer.

In FIG. 3, it can be seen that, in the completely pulled-out endposition, the cage 24, which holds the rolling bodies 20, 22, stillprotrudes from the rear end of the running rail 26 into the hollowprofiled section 30. Particularly when the upper rolling bodies, whichtransfer the weight of the drawer over the running rail 26 onto theguiding rail 12, are constructed in the manner described as rollers 20,it is advisable to have the junction plane, formed between the adjoiningrear end edges of the running rail and the front end edges of the hollowprofiled section when the running rail 26 and the hollow profiledsection 30 are aligned with one another, extend not at right angles tothe pulling-out direction of the running rails, but slightly obliquelyto this direction, as seen in plan view, so that the rollers 20, guidedin the cage 24 at right angles to the pulling-out direction, rollthrough the junction plane obliquely, which leads to a soft, continuoustransfer of the rollers 20 from the running rail 26 to the hollowprofiled section 30 and vice versa, which does not become noticeable inthe form of stoppages or rattling noises.

FIGS. 6 to 8 illustrate a second example of the inventive pullout guide,which is labeled 110 as a whole and largely corresponds to thepreviously described pull-out guide 10, so that it is sufficient todescribe below the changes made. For the identical distinguishingfeatures of the construction, it is sufficient to refer to the previousdescription, particularly since functional identical components of thetwo examples have been given the same reference numbers in the drawings,which are merely preceded by a "1" in the case of the second example.

The basic difference between the pullout guide 110 and the pullout guide10 consists therein that the hollow profiled section 130 is disposed atthe end of the running rail 126 within the carcass so that it can beswiveled about a vertical axis. The control roller 132, which aligns thehollow profiled section 130 over the gutter part of the pullout andpush-in path aligned with the actual running rail 126, is mounted at therear-wall end of the hollow profiled section so that it can be rotatedin such a manner, that its periphery rolls along the inner surface ofthe profiled leg 118 of the guiding rail 112 pointing towards theprofiled leg 114, and moreover beneath the running rail 126, that is, inthe region of the profiled leg 118, lying below the running rail 126 andadjoining the cross member section 116 of the guiding rail directly. Bythe tension on the spring 138, the hollow profiled section 130 is actedupon in the sense of a swiveling away from the profiled leg 114 in sucha manner, that the control roller 132 is held against the profiled leg118.

The control section 136, joined to the end of the guiding rail 112within the carcass, is joined, corresponding to the vertical arrangementof the swiveling axis of the hollow profiled section 130, to the guidingrail in such a manner, that it controls the desired swiveling of thehollow profiled section in a horizontal plane in front of the rear wallof the drawer. For this purpose, the cross member section 116 of theguiding rail is continued in a section 116a, which is continuedarc-shaped over about 90° in the swiveling direction and from the oneboundary edge of which within the carcass a low, strip-shaped region ofmaterial 118a protrudes upwards, along which the control roller 132rolls during the swiveling process of the hollow profiled section 130.

Compared to the profiled leg 118, the strip-shaped region of material118a within the carcass is kept lower in height by such an amount, thatthe hollow profiled section 130 can swivel above the upper boundary edgeof the strip-shaped region of material 118a and the end of the actualrunning rail 126 within the carcass can be pushed over the materialregions 118 up into the vicinity of the rear wall of the carcass. At thesame time, a narrow, strip-shaped section of material 118b once again isbent over from the upper free boundary edge of this material region 118aand overlaps the control roller 132 at the upper side and thus takesover the function of the strip-shaped section 35 of material of thepullout guide 10, that is, the control roller 132 is prevented fromgliding off the strip-shaped section of material, and a malfunctioningis thus prevented.

FIG. 7 also illustrates the oblique course of the junction plane, whichis explained as being advantageous in conjunction with the firstexample, between the rear end of the running rail 126 and the front endof the hollow profiled section 130, which are aligned with one another,illustrated by the oblique course of the junction line T between thesetwo parts, which can be seen in the Figure.

In FIG. 9, a modification of the first example is shown with a hollowprofile, which can be swiveled about a horizontal axis. The modificationmade relates to the design of the guiding rail 12 in the region of thecontrol section, which is a separately produced flat plastic component36 here, which is fastened seated on the end region within the carcassof the flat side of the profiled leg 14 of the guiding rail 12 facingthe drawer. In the case shown, it is fastened in such a manner that,when the control section 36 is being produced, several projectingplastic pins 86 are gated into the flat side of the control section 36facing the profiled leg 14 and are passed through boreholes countersunkinto the profiled leg 14 on the carcass wall side and then deformed bypressing down an extrusion die, heated above the softening temperatureof the plastic material of the control section 35, into the depressionwith formation of a rivet head 88. Alternatively, other types offastening, such as riveted connections by means of metallic rivetspassing through separate, aligned boreholes in the control section 36and the profiled leg 14, are also conceivable.

It can also be seen here that the actual control curve, taking up andguiding the control roller 32, is open or closed there only by theprofiled leg 14 at the bottom side facing the profiled leg 14. At theperiphery, the control roller 32 is guided by the boundary walls 34'34", between the mutually facing surfaces of which the control roller 32is guided forcibly and secured against leaving in the direction of thedrawer by short, laterally overlapping, strip-shaped sections 35 ofmaterial.

Because the control section 36 is produced from plastic, the controlroller 32 can also be disposed closer to the pivoting axis of the hollowprofiled section 30 at the running rail 26, the control curve thenassuming an S-shaped course, which can be recognized in the drawing. Ithas turned out that it is possible in this way to ensure a continuousand stoppage-free as well as noiseless transfer of the rolling bodiesinto and out of the hollow profiled section 30.

The spring, which puts the hollow profiled section 30 under tension inthe first example in the second, swiveled-up position, is omitted inthis example, so that the hollow profiled section 30 is thus guidedforcibly in the control curve only as it approaches the closed positionof the drawer. In all remaining pulled-out positions of the running railrelative to the guiding rail, the hollow profiled section 30 is heldexclusively by its own weight in the position aligned to the runningrail. An unintentional swiveling up of the hollow profiled section 30,which could lead to a malfunctioning, nevertheless is not possiblebecause the hollow profiled section, in the position in which therunning rail is pulled out completely or partially on the guiding railduring the swiveling up, comes into contact with the converted upperedge of the profiled leg 18 of the guiding rail carrying thetransporting paths for the rolling bodies, that is, the hollow profiledsection cannot be swiveled further into a stable, swiveled-up position.

Because of the omission of the spring, which would put the hollowprofiled section 30 under tension into the second swiveled-up position,the additional function of automatically pulling the drawer into theclosed position is omitted in this example. If such an automatic pullingin is desired, it is possible to resort here to known automaticpulling-in devices acting between the guiding rail 12 and the runningrail 26.

What is claimed is:
